WIRE-STRTIPPING TOOL.

Specification of Letters Patent.

.Patentedl Mar. 26, 1918..

To all whom it may concern:

Be it known that I, BERNARD J. GHIA, a subject of the Emperor of Germany, and a resident of the city of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Im provements in Wire-Stripping Tools, of which the following is a specification.

My invention relates to means for removing the covering or insulation from wire, and has for its object to provide a device for that purpose and others which shall be simple, cheap, convenient in. manipulation, and ellicient.-

The invention consists in the novel construction, arrangement and combination of elements and parts as shown in the accompanying drawing and hereinafter described.

In the said drawing, Figure 1 is aperspective view of my invention; Fig. 2 a sectional view on the line 29. of Fig. 1, looking toward the right of said figure; and Fig. 3 is an end view, looking in the opposite direction.

In carrying my invention into efi'ect in the embodiment thereof which I have chosen for illustration in the drawing and description in this specification, I provide a device of the general form best shown in Fig. 1, constructed of hard steel or other suitable material, having a main body portion 4:, having at one end a downwardly projecting bifurcated portion forming a pair of teeth 5, and having the other end bent approximately in a semicircle forming a hook 6, bearing a pair of studs 7. The inner and outer edges of the teeth 5 are sharpened to a cutting edge, and the V-shaped opening between said teeth is preferably not brought to an acute angle at its nearest point, but

is sha ed as best shown in Figs. 2 and 3, the si es of the narrow portion of the opening being approximately parallel for a short distance and the extreme inner end of the opening being rounded as shown. The shape and size of the hook 6 is such as to receive the last finger of the operators hand when the tool is in use and the main portion 4 isgrasped in the hand, said hook thus cooperating to permit a firm hold on the tool by the user.

In electric wiring and other work In which insulated wire is employed it is he quently necessary to strip from a portion of the wire its insulating covering, and where duplex Wire is being operated with it is of course first necessary to separate the two w res or remove the outside covering of the pair, before the insulation upon either can be reached. It is also frequently necessary 1n such work to form a hook or a loop upon the end of the wire. I have found in practical use that a tool embodying my invention 1s entirely eificient in performing the said. operat ons and others. The operation of the mvention when so used is as follows:

When duplex wire is being used and it is desired to separate the twostrands of wire, the tool is used to sever the outer coating by a stroke of the sharp cutting edge on the outer part of either of. the teeth 5, thus freeing the wires from their outer covering and permitting them to be bent apart as far as desired. To remove the insulation from a single wire, it is placed in the opening between the teeth 5, pressed up into the small part of the opening as far as may be desired, and the tool given a half rotation, more or less, around the wire, whereby the insulation is quickly cut through to the wire, and then the tool is moved lengthwise of the wire, which strips oi the portion of the insulation which has been severed by the cutting edges. It will be understood that the body of the tool is grasped in the hand, the last finger lying within the curve of the hook portion 6.

When it is desired to bend the wire or to form a loop therein, it is placed between the studs 7 and bent around until a circular loop or such other form as is desired has been produced.

The advantages of my invention will be obvious from what has been above said with regard to its construction and mode of oper ation.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent isas follows:

In an article of the kind described, a body portion provided with teeth projecting laterally from one end thereof, said teeth having cutting edges. said edges being parallel at their inner ends and divergent at their outer ends, and a portion extending later- In witness whereof I havehereunto signed all from the opposite side of the other end my name this 6th day of March, 1917. of said body portion from saiditeeth, and

bent into semlcircular form, whereb it is BERNARD C 5 adapted to be asped to draw sai body Witnesses:
